摘要：

目的了解SRB1在白念珠菌氟康唑耐药株和敏感株表达差异，探讨与白念珠菌耐药性的关系。方法使用同一亲本来源的白念珠菌氟康唑耐药株CA-16和敏感株CA-3为研究对象，采用实时荧光定量RT-PCR的方法扩增各菌株的目的基因SRB1、CDR1、ERG11，观察各菌株目的基因表达情况。结果与白念珠菌氟康唑敏感株CA-3相比，在mRNA水平氟康唑耐药株CA-16的SRB1和耐药基因CDR1、ERG11表达升高，SRB1、CDR1、ERG11表达水平差异具有统计学意义（P<0.05）。结论白念珠菌SRB1的表达增高和白念珠菌对氟康唑耐药密切相关，SRB1可能是一个新的耐药候选基因。

Abstract:

Objective To investigate the differences in the expression of Candida albicans SRB1 in Candida albicans fluconazol resistant strain and sensitive strain,and to explore the relationship between SRB1 and drug resistance in Candida albicans.Methods Two Candida albicans strains were from a same parent.We used real-time RT-PCR to observe the expression of the target genes of SRB1,CDR1,ERG11 in Candida albicans fluconazole resistant strain CA-16 and sensitive strain CA-3.Result Compared with CA-3,the expression of the mRNA of SRB1 and drug resistance gene CDR1,ERG11 in CA-16 increased.There was significant difference in the expression levels of SRR1、CDR1 and ERG11 (P<0.05).Conclusion The increased expression of SRB1 and the Candida albicans resistance to fluconazole was closely related,and SRB1 might be a new candidate genes associated with drug resistance.

Key words: Candida albicans, drug resistance, gene, PCR, SRB1
